And to think I was just going to come and tell you that I actually read those first 8 pages again, and hence forth have a better understanding of this process!
Two phrases from television and a movie have now come to focus in my tiny little migraine plagued brain:
The first comes from the Honeymooners something like
"To the moon Alice!"
Which now seems like BudP would be more appropriate instead of Alice.🙂
The second I believe comes from Ferris Buellers Day Off:
Again something like "Pardon my French, but you're an &$*#@hole"
You know I am Kidding I hope😀
Omg, you had me rolling on the floor. You are a comedians comedian. The more of your tortuous expose' I read, the more I cracked up! Funny thing was, I was actually able to discern from your increased efforts to discombobulate me, that you were re- explaining the same theories that had so taxed my intellect the first time!
I meant what I said. We need guys like you in the world, especially if they are both smart, and funny.
And I will have some more questions, I just need to read some more, and stop laughing so hard.

Same as any other configuration.
EnABL is not going to solve speaker interactions due to location, crossover point, nodal steering and driver phase mis matches. It will make more low level information available and in the case of some dome tweeters raise the efficiency a bit, along with eliminating phase lag across the bandwidth they cover. This can aggravate phase mismatch and require a crossover redesign.
With MTM, the same "squeeze" is applied to the highs, but if you treat the baffle too, then the drivers will blend within an inch of the baffle surface, in most cases. The result is an extremely coherent sound with pin point imaging and rock solid position in the portrayed sound field.
What EnABL will not do is alter the "voice" of the drivers. Frequency response and THD do not seem to be altered. Im interactions between cones and phase plugs can be eliminated, but the system is not going to "sound better". Just a less confused presentation, with gobs of detail in large, coherent spaces and with less false information left, to get in the way of the music, that was the original reason for all of this foolishness in the first place.
Just very satisfying to listen too.

OZMikeH,
Very very serious. To date it has worked for everyone who has tried it. Can't say it will work for everyone, but, yea, well worth a try. Plus the tie down straps are very useful, especially for any children Mongo might have influence over....

When I get a chance I'll past pictures of a couple of drivers I'm considering for treatment. One is a Vifa/JBL 4" treated paper mid-woofer that was on clearance sale at Patrs Express a year or so ago. The response plot looks as though it might have a few problems with breakup at the upper end of its range. The other is the Tang Band W4-654SE, ane of the less expensive full-rangers, with paper cone and an aluminum phase plug.
Hi wrenchone,
Be glad to treat them to a virtual EnABL for you. I suspect you have looked at the earlier PDF's for Chris. If you duplicate that angle it will be a piece of cake to do.... for me, and just a few hours of effort on your part, to turn them into reality. I am quite sure you will like the results and am pleased to see multi driver systems being explored, in addition to the full range drivers we started with.
Until the Lowther DX 4's showed up at my door, from Limono, I had never done any work on a full range driver, other than the original Ohm F's. All of the intervening systems have been multi driver ones and are frankly still my favorite's to treat.
Much simpler problems to solve and with just as good, if not better overall results. I must admit though, that without the Lowthers and follow on full range drivers, I would not have been forced to think about the problem that required Electron Pools as a solution, so I am not complaining.

Bud,
I remember Vifa BC11SG06-12 being among the PE buyouts. I'm interested in a pattern for them as well. As they are an OEM and no longer available, the closest dimensional description I find on the web is at the bottom of this link:

Wrench,
The response graph would be different. Does this fit the description of your drivers?

An externally hosted image should be here but it was not working when we last tested it.
That sort of looks like the driver in question, though the numbers aren't anywhere close to the actual part number on the driver itself.
Parameters: 35WRMS Power Handling, Znom 4 ohms, Re 2.95 ohms, Fs 65 Hz, SPL 88dB/1W, Vas, 0.16 ft^3, Qms 1.44, Qes 0.34, Qts 0.27, Xmax 3.5 mm. Attached is the freqency response. Note the big notch and gereral midrange rastiness. I was thinking of using this in an MTM ported design with 0.5 cubic foot enclosure, but the low Vas makes the bass peak too pronounced, and I dont like the midrange rollercoaster. I have a 4" Tang Band full range with polypropylene cone in mind (W4-1052SD) that has a much smoother response and is also beter suited for the enclosure size. However, these guys may be useful for another project if I can smooth them out.

Thanks Bud
The Vifa pattern will be helpful.
I have built left, center and right mtm's that include the Audax TM025F1 1" textile dome tweeter.

Can you suggest a pattern for the tweets?
